In addition, pursuant to the indenture, dated as of July 17, 2008 (the “Indenture”), between Walgreens and Wells Fargo Bank, National Association, as trustee (the "Trustee"), on July 9, 2015 notices of redemption were given to (i) holders of 1.800% unsecured notes due 2017 (CUSIP No. 931422AJ8) (the “2017 Notes”) and (ii) holders of 5.25% unsecured notes due 2019 (CUSIP No. 931422AE9) (the “2019 Notes”), in each case, issued by Walgreens under the Indenture. As a result, on August 10, 2015 (the “redemption date”), the 2017 Notes in the aggregate principal amount of $1.0 billion will be redeemed in full and $750 million aggregate principal amount of the 2019 Notes will be redeemed. The partial redemption of the 2019 Notes will result in $250 million aggregate principal amount of 2019 Notes remaining outstanding immediately after the partial redemption is completed. The redemption price with respect to each of the 2017 Notes and 2019 Notes will be equal to 100% of the aggregate principal amount of such notes to be redeemed, plus an applicable premium, plus accrued interest thereon to, but excluding, the redemption date.

As such, Walgreens’ guarantee of the WBA notes (as described above) will automatically terminate, and the obligations of Walgreens under the Walgreens guarantee will be unconditionally released and discharged. This report does not constitute a notice of redemption with respect to or an offer to purchase or sell (or a solicitation of an offer to purchase or sell) any securities. Additionally, on July 9, 2015, Walgreens Boots Alliance announced that it had acquired Liz Earle Beauty Co. Ltd, owner of the Liz Earle skincare brand.
